BEYOND HRC65 8D Solid Carbide Drill with Internal Coolant (17.0–18.9mm)
The BEYOND HRC65 8D Solid Carbide Drill is engineered for high-efficiency and precision drilling in hardened materials up to HRC65. With an 8×D length-to-diameter ratio and internal coolant channels, it provides smooth chip evacuation, excellent heat resistance, and extended tool life, making it ideal for deep-hole drilling applications in molds, dies, and aerospace parts.
🔧 Product Features
- High Hardness Carbide: Premium ultra-fine tungsten carbide material ensures superior wear resistance and rigidity.
- Internal Coolant Holes: Dual-channel coolant design improves heat dissipation and chip evacuation during deep drilling.
- 8×D Deep-Hole Design: Stable performance even under heavy load conditions for long drilling depth.
- Optimized Cutting Edge: Sharp edges minimize cutting force and improve hole roundness and finish quality.
- High-Performance Coating: Nano-coating extends tool life, prevents adhesion, and enhances surface finish.
